Interesting... That reminded me of a book in my stash I picked up a while back and never looked at, until now... It is Materials and Techniques for Electron Tubes By Walter H. Kohl. (1960 Reinhold Publishing co.) Kohl was Senior Engineering Specialist, Special Tube Operations Sylvania Electric Products, inc. (A subsidiary of GTE) This book is a Gold Mine, if you are interested in the materials used in the making of tubes. There is a whole chapter (70 plus pages) on glass itself, and another chapter on joining glass to metals. A chapter on mica and individual chapters on all the different metals used. And enough charts and graphs and equations to make you dizzy.
A quick glance told me that yes, much of the glass used in tubes came from Corning, (In Corning NY of course, between Bath and Elmira) and there were some 150 different formulations of PYREX. The other big glass supplier was Kimble made by Owens Illinois.
I'm going to need to go back to school to understand this book...
